Microcrystalline cellulose (MCC) was prepared from sugarcane bagasse (SCB) after alkali extraction with sodium hydroxide (NaOH). The MCC treated methylene blue solution. Batch experiments were performed to investigate the effect of contact time, initial dye concentration, pH and adsorbent dosage on adsorption. result shows that adsorption onto influenced by dose, time values. For higher removal...

introduction: the objective of this study was, wastewater quality investigation and removal efficiency of contaminants from the wastewater tile factory by using  coagulants includes ferric chloride, ferric sulfate and ferrous, aluminum sulfate and poly aluminum chloride in order to reuse it in the processing line. methods: this is an applied study. with regard to shiftwork schedules of the fact...

UNLABELLED Vancomycin is widely used in haemodialysis (HD) patients for treating infections of vascular access due to St. Aureus. To avoid subtherapeutic levels it is important to know the adequate dosing in patients undergoing haemodialysis with high flux membranes. OBJECTIVE The aim of this study was to evaluate whether HD patients treated with 1 g intravenous (IV) vancomycin reached optimu...

Beam hardening filters have long been employed in X-ray Computed Tomography (CT) to preferentially absorb soft and low-energy X-rays having no or little contribution to image formation, thus allowing the reduction of patient dose and beam hardening artefacts. In this work, we studied the influence of additional copper (Cu) and aluminium (Al) flat filters on patient dose and image quality and se...

Induction of hyperbilirubinemia in experimental rabbits by phenylhydrazine was optimized in terms of dose, dose interval and number of doses using response surface methodology. Central Composite Design was employed using five levels for each of the three input variables. Degree of hyperbilirubinemia was measured in terms of bilirubin level in serum of animals. A dose dependent significant eleva...

We successfully treated 3 consecutive patients who had nonneutropenic rhinocerebral zygomycosis, by use of subcutaneous granulocyte-macrophage colony-stimulating factor therapy combined with traditional surgical and medical treatment. All patients are currently free of disease. Granulocyte-macrophage colony-stimulating factor should be considered as adjuvant therapy for rhinocerebral zygomycosi...

introduction: esophageal cancer is one of the most frequently occurring cancers in iran and having a  high  incidence  rate  among  other  countries.  radiotherapy  is  one  of  the  three  methods  (surgery,  radiotherapy and chemotherapy) for radical or palliative treatment of esophageal cancer. in this method  of treatment, the organs such as heart and spinal cord are regarded as organs at r...

introduction radiation exposures from diagnostic medical examinations are generally low and are almost always justified by the benefits of accurate diagnosis of possible disease conditions. therefore, entrance skin dose (esd), body organ dose (bod), and effective dose (ed) from adult patients undergoing routine thorax posterior-anterior (pa) and thorax right lateral (rlat) were estimated in uni...

background: changes in body composition may be used for monitoring progression/ regression of a disease. prompt γ-rays in vivo neutron activation analysis (ivnaa) has been widely used for the measurement of body composition in recent years. objective: in this paper, we tried to improve the safety of ivnaa operator. methods: the most important factor for reducing the operator receiving dose is t...
